Dumbo (1941)
I used to watch this film a lot when I was a kid; it was odd that I didn't really think much of an elephant and mouse getting drunk, crows who behaved like racist stereotypes and an elephant being declared insane for trying to protect her child.
I find myself remembering this in a lot of detail, and have watched it a few times as an adult. Timothy Mouse is a great sidekick in this film, particularly as he seems to get most of the film's lines.
My favourite sequence will always be "pink elephants on parade" though.
Did I mention that this is my all-time favourite Disney flick? I'm not sure if I'll ever bother with Tim Burton's remake.
